Hadleigh Schwartz
I’m a PhD student in Computer Science at Columbia University, advised by Xia Zhou. I’m fortunate to also work with Dan Rubenstein and Changxi Zheng. My research develops content authenticity and media provenance technologies, with a current focus on audio, image, and video. I’m a recipient of a Columbia SEAS Presidential Distinguished Fellowship and an Amazon CAIT PhD Fellowship.
Previously, my research focused on optical sensing and communication. I’ve also interned at NASA’s Jet Propulsion Lab, working on simulation for vision-based spacecraft landing. I completed my B.A. and M.S. in Computer Science at the University of Chicago, advised by Heather Zheng at the SAND Lab.
